I seek efficiency in my life :). Not always the best thing but when it comes to organizing things, it works out to stay organized.  Wasted time and space are not high on my list.  Well, good news, if you have a space for this, get it.  Trust me, no more getting down on your hands and knees to reach WAY back for those items that you may not access all that often but it's a pain b/c you have to take everything out 1st to get to that one dish / appliance.  Easy install, smooth enough even w/ weight on it!
